摘　　要：不平衡保护是预防电容器组故障的主要保护,文章介绍了不平衡保护的方式,分析了不平衡电压产生的原因,并通过实例对并联电容器组不平衡电压进行了模拟仿真、分析以确保不平衡保护整定值的可靠性。Unbalance protection is the main protection to the fault of capacitor banks. In this paper the way of unbalance protection is introduced, the cause of unbalance voltage is analyzed and unbalance voltage value of the shunt capacitor bank is simulated and analyzed through actual example so to assure reliability of the unbalance protection setting.
